Results

 The previous chapter described the method by which the simulations were performed. This chapter presents the results of these simulations. These include the basic model results for individual clocks satisfying the wander masks as well as the wander at various points in the reference chain for both the original and extended clock models. The masks define the maximum low frequency phase fluctuations that may be present in a synchronisation signal. They are expressed in terms of two measures, TDEV measuring the underlying noise present in a signal and MTIE the transients.

Model parameters allowing the clocks to satisfy the masks are also proposed. Initial data highlighting a potential problem with one of the filters is presented, Simulations of filter A in the basic model are also given as well as graphical analysis from the symbolic mathematics package Mathematica . These substantiate the belief that there is a factor missing in the filter transfer function for filter A. The appropriate use of certain SPW blocks is also verified by reference to additional simulations.
